Would you choose structural exclusion services over traditional traps to keep rodents out of your home?
Rywen Insulation Inc. offers structural rodent exclusion services for San Leandro homes by sealing entry points without the use of poison or traps. Homeowners can request same-day written estimates for services that target common gaps in attics and crawl spaces.
Why it matters
Rodents often enter homes through structural gaps that are difficult for residents to spot from the ground. Identifying and sealing these access points is a non-toxic method for securing living spaces against infestations.
Rywen Insulation Inc. operates under California contractor license #1140414 and provides same-day written estimates for residents. Mice can enter through openings the size of a quarter, while rats require only a gap the size of a half dollar.
The players

A contractor specializing in structural rodent exclusion that avoids the use of chemical poisons and bait traps.
The details
The exclusion process involves a professional inspection of the attic and crawl space, where crews use photo documentation to identify hidden entry points. Technicians then seal these gaps using galvanized steel mesh, sheet metal, and other rodent-rated materials. This physical barrier approach avoids the use of poison, bait stations, or traps.

The Home Front
Structural exclusion represents a shift toward permanent, non-toxic building maintenance over traditional pest control methods like trapping or chemical baiting. Using physical barriers like sheet metal and mesh is consistent with modern building codes focused on pest-proofing.
Homeowners should visually inspect eaves, vents, and foundation gaps for holes as small as a quarter. If gaps are found, contact a licensed professional to perform a detailed audit of your attic and crawl space.
The takeaway
Closing structural gaps is the most effective way to prevent rodents from entering your home. Residents can contact the service provider at (415) 770-0342 to schedule an inspection and identify potential access points around their foundation or roofline.
